Abstract

Hydrodenitrogenation (HDN) of quinoline in the presence of H₂S, H₂O and NH₃ was carried out in the liquid phase in a fixed bed catalytic reactor at 7.0 MPa and 330, 350 and 375 °C. The commercial catalyst NiMo/γ-Al₂O₃ was used as supplied without reducing its size and was presulphided before the tests. Strong internal pore diffusional resistance was observed in the catalyst pellets. At 375 °C the effectiveness factor was calculated to be 0.6. The overall kinetics followed pseudo-first-order behaviour with respect to total nitrogen concentration. The individual and combined effects of H₂S, H₂O and NH₃ on the overall rate constants were also measured. The combined effect caused a net increase in the overall HDN rate. The results from this flow reactor were compared with previous batch reactor data where the intrinsic kinetics had been determined. Finally, the catalyst deactivation behaviour in the presence of H₂S, H₂O and NH₃ in this HDN reaction was investigated.
